##### Density Estimation for Circular Data

Computes a kernel smoothed estimate of the probability density for angular data.

- Keywords
- smooth, nonparametric

##### Usage

```
circdensity(x, sigma = "nrd0", ...,
bw = NULL,
weights=NULL, unit = c("degree", "radian"))
```

##### Arguments

- x
- Numeric vector, containing angular data.
- sigma
- Smoothing bandwidth, or bandwidth selection rule, passed to
`density.default`

. - bw
- Alternative to
`sigma`

for consistency with other functions. - ...
- Additional arguments passed to
`density.default`

, such as`kernel`

and`weights`

. - weights
- Optional numeric vector of weights for the data in
`x`

. - unit
- The unit of angle in which
`x`

is expressed.

##### Details

The angular values `x`

are smoothed using
(by default) the wrapped Gaussian kernel with standard deviation `sigma`

.

##### Value

- An object of class
`"density"`

(produced by`density.default`

) which can be plotted by`plot`

or by`rose`

.

##### Examples

```
ang <- runif(1000, max=360)
rose(circdensity(ang, 12))
```
